AUTOMOBILE WINDOW.

ApplicationVK filled` February 28, 1921. Serial I[\`Ic .'i448,450.

l'o all lwhom 'it may concern.' Be it known that we, JOSEPH S. GREENLEYand JOHN A. NAIsMiTrr, citizens of the United States, and residents ofSan Jose, 5 in thecounty of Santa Clara and State of California, haveinvented certain new and useful Improvements in Automobile Windows, ofwhich the followingiis a specification. y

Our invention ielates particularly to'suspension and positioningmechanism for the the sliding windows of automobile tops.

It is the object of our invention to provide a simple, effective, andpositivelyk acting mechanism whereby a sliding window may be moved intoa predetermined position and securely held vagainst accidentaldisplacement and prevented from rattling. .It is another object of ourinvention to provide a means cooperating with the above. mentionedmechanism whereby a weather proof joint is secured at the bottom -edgeof .the window when in a predetermined position. It is a further objectof our invention to 25 provide a device of the character indicated thatwill permit the use'of unbroken tracks, and in which the number of partsof diien ent conformation are reduced to al minimum.

In the drawing: Figure 1 is, ai'i'interior side elevation of anautomobiletop frame showing its sliding windows mounted in ac= cordancewith this invention. n n

Referring more particularly to the drawing, 1 indicates a portion of theframework of an automobile top and 2 the upper side CJD edge oftheautomobile body, a stationary window being' shown at 3 and movablewindows at 4 and 5 respectively, the movable windows being guided attheir lower edges by separator or guide members;

At 7 is shown a track for window 4, its forward end terminating'adjacent to the forward 'end' of the window as indicated in thediagrainmatical illustration iii-Figure'. At 8 is shown a track forwindow 5 and ei:-k tending tlie full length 4of frame 1 and ai rangedparallel with track 7 throughout the length of the'latter. f Thesetracks `7 and S are mounted upon thesides ofjsupporting strips 9 and 10respectively, the'latterbeing 5 secured to the under surface of theupper portionvof the frame as shown.

Each window 4 and 5 is mounted on its` respective trackby means of apair of hangers'as 11-11 and12'12engaging the track Tlf' and extendingdownwardly into cases 18-13, 11i-14 set ,inf windows 4 and 5 in therelative position shown. The cases 13-14 and the windows in which theyare mounted are formed toeplovide pockets' as l15 and 1G, The hangersyare provided withv springsl as `17-17 and18-18 inserted between theirlower ends andl the upper vends'oftheir respective 'pockets whereby thewindows are normallyheld in a raised position as indicatedin dottedlinesl at 19; While in this raised position the windows may be movedfreelyback and forth on their respective tracks.

As a means for securing the windows 4 5 5J in an advanced or retractedposition we provide a number of cam elements as 20-20 and 20a-20a, 21-21and 21a- 213, 20h-20h, 21?-21". These elements, are arranged in pairsand preferably with one member of l each pair as .20 having a grooveformed'` thereinr as at 22, and the other member as 20 haviiigan edgeformed thereon as 23 toengage the .groovel 'in .theother cam inconjunction with wli'ich'itoperates.y The 4pairs '5" of cams on eachwindow,`asf20-20a, 20-20a,

n are arranged one on each side of the vertical plane in which thewindow slidesjso that when window 5 is moved from the advanced to theretracted position the fixed cams EN 20V-'2O on its-upper edge passfreely to engagement with cams L-2Ob also olset on strip 10,V the rea-rcamV 2O freely passing the forward cam 201.

In like manner when window 4 is moved rearwardly the rear camQl passestheY forward cam 2lb and the ytwo cams Qldl simultaneously engage thetwo cams 2lb- 21k Y Since in each case one cam oi'each pair is result isthat when window is moved suffi- Civ ciently far .p in either direction'theY lcams thereon engage a iXed pairA oi cams and move over the curvededges thereofv and rdrop'into engagement therewith, the springs and thetorni of the cams cooperating to securely lockv the window in position.ln this manner window Ll is held in a forward `'position in engagementwith cams 21M-2l,

i ment.

and in a retracted-position in engagement with cams 21h-2lb Likewisewindow 5 is held in a forward position in engagement with cams 20a-QOH,and in a retracted position in engagement-with cams 20h-20h.

l/Vhen onejcam passes over the shoulder of the other whereby the twovmay Vengage each otherasdescribed, the window is caused to lower fromits raised position to a point below the level'oi Vits'linal position,and then raise slightly to the said'tinal and .locked position. Thismovement would ordinarily leave an open space between the bottom or thewindow and the top of the automobile body ordoor edge. weather proofjoint at this `point we provide a bead 24: upon the upper edge oi theYdoor or automobile body so that the window may be lowered and thenslightly raised as it settles into a locked position at the end oi itsmove- Theproportions of the lbead must conform, of course, to theproportions oi'. the

concave and convex portions oi' the engaging l cams.

It is particularly pointed out that in this construction the window issecurely held in ay fixed position at either end of its range oi'movement or, indeed, wherever cams are rarranged to engage the cam onthe window moved. For instance, in this construction the cams may be soarranged that a forward window as 5 may be moved to engage cams as shownin dotted linesA atEZlOc-QOc in Fig# ure 2- if it is not desired to moveit back to the-limit of its ope'n-position.'l Another vpar-r ticularlyadvantageous feature of this construction is that no special alterationis requiredin the track structure ,and the hanger shoes may be made 'inYany form to move In order to provide `a imanes freely in the track.Furthermore, all of the hangers may be made identical in form andconstruction, and all of the pairs of cams Y may also be made identicalin form and construction. f Y

It is to bek understood, oi course, that while we have herein shown anddescribed one particular embodiment of our invention,
